1 General Description
The F75198 is the USB Dedicated Charger identification circuit which is so smart to
recognized most of mainstream handheld devices. It allows device to draw a current as much
as using an original adapter.
The F75198 support most of the USB Battery Charging Specification worldwide, including
BC 1.2, Apple® charging spec (for i-Pad & i-Phones) and specs for Samsung Galaxy Tab.
By setting the USB Data pins (D+/D-) to the required voltage levels, then the charging device
will recognize the voltage levels, and starts to draw the current to charge. It also equipped with a
select pin (SEL) allows users to selection desired charging current for apple devices.
The F75198 is suitable for all charger products using USB interface. It provides enhanced
ESD protection up to ±8kV on the DP and DM. With the compact SOT23-5 Package, it require
minimum external circuits, which can reduce develop & production cost dramatically.
